First of, i love the game. Its easy to learn but hard to master. Especially when you start drawing students from other places.

That said, a few things that could be modified/changed/added to.

First up, the kitties. Yes i love em, they are awesome, however as is they serve no function. Have the kitties hunt vermin in the school if its to dirty or something. And let students pet the cats. Also, the adopt a kitty thing should be a bit more rare. As it is now you can en up with more cats than students if you play long enough.

Second: the excursion festival event quest. Maybe add a destination for the class to go on each to discover map bits? because eventually you'll have it all discovered. and students will get bored of going to the farm. Other excursion ideas: museum, art gallery, park, the capital and its historical buildings. the pool (in summer?) to name a few.

Third: Sakura trees, can we please get them to place our selves?

fourth: Rail station, if i'm investing in it, i expect to be able to clean up the area around it so it doesn't look like a dump.

fifth: can i have it that the moon cakes don't make my principal as round as the moon? frankly how fast it maxes your weight is a lil ridiculous. And nothing slims your toon down again. And frankly with how much teachers, researcher and such all walk around. they shouldn't have that effect so extreme. (Also its a lil offensive to people who struggle with body weight irl.)

six: wintertime: snowball fight? please? Surely that is a thing everywhere that snow falls right?

Thats it for now.

PS: Love the DLC stuff, but some are hard to implement in a new game. Keep up the great work.
